2017-09-16Refactor: Modernize disallowed copy constructors/assignmentDan Raviv
Use C++11's better capability of expressing an interface of a non-copyable class by publicly deleting its copy ctor and assignment operator instead of just declaring them private.

2017-06-01Upgrade from per-tx database to per-txoutPieter Wuille
2017-06-01Reduce reserved memory space for flushingPieter Wuille
As the maximum amount of data that can be pulled into the cache due to a block validation is much lower now (at most one CCoin entry per input and per output), reduce the conservative estimate used to determine flushing time.
2017-06-01Switch CCoinsView and chainstate db from per-txid to per-txoutPieter Wuille
This patch makes several related changes: * Changes the CCoinsView virtual methods (GetCoins, HaveCoins, ...) to be COutPoint/Coin-based rather than txid/CCoins-based. * Changes the chainstate db to a new incompatible format that is also COutPoint/Coin based. * Implements reconstruction code for hash_serialized_2. * Adapts the coins_tests unit tests (thanks to Russell Yanofsky). A side effect of the new CCoinsView model is that we can no longer use the (unreliable) test for transaction outputs in the UTXO set to determine whether we already have a particular transaction.

2017-03-31Make threshold for flushing more conservative.Alex Morcos
Always leave a reasonable buffer of 50MB for usage from newly connected block (once over 50%) and increase the high water mark buffer to 200MB.
2017-03-31Lower default memory footprint slightlyAlex Morcos
2017-03-31Make pcoinsTip memory calculations consistentAlex Morcos
Since we are more accurately measuring pcoinsTip peak usage at twice the current in dynamic usage, it makes sense to double the default (this will lead to the same effective usage and peak usage as previously). We should also double the buffer used to avoid flushing if above 90% but still sufficient space remaining.

2016-11-07Get rid of nType and nVersionPieter Wuille
Remove the nType and nVersion as parameters to all serialization methods and functions. There is only one place where it's read and has an impact (in CAddress), and even there it does not impact any of the recursively invoked serializers. Instead, the few places that need nType or nVersion are changed to read it directly from the stream object, through GetType() and GetVersion() methods which are added to all stream classes.

2016-07-06Bump `-dbcache` default to 300MiBWladimir J. van der Laan
Also cap the allocation for the leveldb-specific cache for the UTXO set to 8MiB. This avoids that the extra cache memory goes to the much less effective leveldb cache instead of our application-level cache.
2016-04-15Break circular dependency main ↔ txdbWladimir J. van der Laan
Break the circular dependency between main and txdb by: - Moving `CBlockFileInfo` from `main.h` to `chain.h`. I think this makes sense, as the other block-file stuff is there too. - Moving `CDiskTxPos` from `main.h` to `txdb.h`. This type seems specific to txdb. - Pass a functor `insertBlockIndex` to `LoadBlockIndexGuts`. This leaves it up to the caller how to insert block indices.
2016-04-15txdb: Add Cursor() method to CCoinsView to iterate over UTXO setWladimir J. van der Laan
Add a method Cursor() to CCoinsView that returns a cursor which can be used to iterate over the whole UTXO set. - rpc: Change gettxoutsetinfo to use new Cursor method - txdb: Remove GetStats method - Now that GetStats is implemented in terms of Cursor, remove it.

2014-09-23Get rid of CCoinsView's SetCoins and SetBestBlock.Pieter Wuille
All direct modifications are now done through ModifyCoins, and BatchWrite is used for pushing batches of queued modifications up, so we don't need the low-level SetCoins and SetBestBlock anymore in the top-level CCoinsView class.

2013-11-10Cleanup code using forward declarations.Brandon Dahler
Use misc methods of avoiding unnecesary header includes. Replace int typedefs with int##_t from stdint.h. Replace PRI64[xdu] with PRI[xdu]64 from inttypes.h. Normalize QT_VERSION ifs where possible. Resolve some indirect dependencies as direct ones. Remove extern declarations from .cpp files.

2013-11-01Do not use the redundant BestInvalidWork record in the block database.Pieter Wuille
As block index entries have a flag for marking invalid blocks, the 'best invalid work' information can be derived from there. In addition, remove the global from main.h
